jupyter小部件扩展没有呈现ui项。尝试更新客户端并启用Widgetsnb扩展名，但代码如下：

!pip install --upgrade jupyter_core jupyter_client
!jupyter nbextension enable --py widgetsnbextension

from IPython.display import display
button = widgets.Button(description="Click Me!")
display(button)

def on_button_clicked(b):
    print("Button clicked.")

button.on_click(on_button_clicked)

呈现：

Enabling notebook extension jupyter-js-widgets/extension...
      - Validating: OK
Button(description='Click Me!', style=ButtonStyle())

案文如下：

Button(description='Click Me!', style=ButtonStyle())

，而不是呈现UI按钮。

还需要另一个图书馆吗？

jupyter

python

jupyter-notebook

来自install.html：

问题:当我显示一个小部件或交互时，我只看到一些文本，比如IntSlider(value=0)或交互式(children=(IntSlider(value=0，description='x'，max=1)，Output()，_dom_classes=(小部件-交互，))。怎么啦？答:如果小部件控件不可用，则打印小部件的文本表示。这可能意味着小部件JavaScript仍在加载。如果消息在朱庇特笔记本或JupyterLab中仍然存在，这可能意味着小部件JavaScript库要么没有安装，要么没有启用。有关安装说明，请参阅上面的安装说明。

页面刷新固定问题为我。我认为我的问题中所提到的安装仍然是必需的。

在我的例子中，我不得不再次运行jupyter笔记本中的细胞。在选项卡 Widgets 中，选择Save小部件状态应该在每次打开笔记本时呈现小部件，而不必重新运行它。
